Question
Solution
Average number of total students from school A = (640 + 800 + 500 + 700 + 900 + 750)/6 = 4290/6 Average number of total students from school B = (550 + 820 + 600 + 750 + 500 + 480)/6 = 3700/6 Required ratio = 4290 : 3700 = 429:370 The ratio of the average of the total students from school A to the average of the total students from school B =370:429
